Check your remediation contractor's experienced and references.

AND CALL THE REFERENCES! Don't take anyone's word for it when it comes to shelling out thousands, perhaps tens of thousands of dollars for remediation work. Ask for references for jobs that are at least 10 to 12 months old. Why? Because every mold remediation job looks great as soon as it’s finished. But if remediation work is not done correctly, it can take several months to realize it. As a rule, if mold does not reoccur in that time, the work was done correctly. A remediation contractor who has nothing to hide, has no problem giving you references. If a contractor gets offend by your request, that’s a good indication that you don’t want to use that contractor.
